Assuming 10% prop slip, that's what I calculate also.

51 mph at 15 % , and 48 mph at 20%.

Would a SS prop reduce slip?

=================================

It's hard to say, but it might. The advantages of stainless over
aluminum are structural rigidity (less flex) and surface smoothness
(less friction). Improving either quality could decrease slip which
would have the effect of increasing speed at comparable RPMs.
